WIDE BAND ACTIVE CIRCUIT THREE-PORT CIRCULATOR FOR ULTRA-HIGH FREQUENCIES AND MICROWAVES

摘要

An active circuit one octave circulator made of three identical arms interconnected at the three-ports, each arm consisting of a gyrator comprising voltage and current single stage transistorized amplifiers, the impedance at each port being matched with the standard impedance of microwave circuits, and capacitive interconnecting means are provided at each end of the arms and between the two amplifiers. The circulators are designed as microwave integrated circuits.
